It's a daily ritual. Annoyed Londoner telling-off and shoving ignorant tourists to stand on the right-side of the escalator as they hurry down the left-side on the way to work (or back from it). But why do we do it? Well a piece of restored video from a 1928 film aptly-titled
Underground may have the
answer. The video taken inside London's Waterloo Tube station shows passengers standing on the right-side because of the diagonal-shaped step at the end of the escalator, that made it easier to get-off with one's right foot first. The film is being shown at the
53rd London Film Festival and contains some of the earliest video footage of the world's oldest and most famous underground railway. And in case you weren't aware of it, make sure you never stand on the left-side on your next visit!
